For me it is D'Amour. He has all the tools to be a top defenceman weather or not he can put it all together is yet to be seen. The fact that he is a great skater, has a lazer shot, can play both ends of the rink with a top knotch game. He can Fight, Hit and clear the front of the net with his huge frame. Sure Doherty has upside but I don't see his upside being any better then D'Amour and for me I think D'Amour's game is way ahead of Doherty's.
